take off the governer. it the best thing to do, but the hard part is finding it.

Isn't the governer programmed into the engine management software in BMWs? I was under the impression it was actually a pretty big deal to disable it - to the point of virtually replacing the engine management system?

Ah no.

You go to any good tuning place and they just edit top speed out of the ECU. Is pretty easy, and not too pricy.

or you could rip the guts out of it and put an older motor in lol

And in the process you'd be ruining the world's baddest production sedan.

Oh, okay - I must be thinking of another vehicle.

Saw off the metal piece beneath the accelerator, so you can press it down deeper.

Hey M5Power, wanna know the top speed of the M5?
Try to calculate in Miles Per Hour:

No, vat_man is right. Taking down the top speed barrier of an M5 is extremely difficult. No dealer could do it, that's for sure, although there may be skilled BMW mechanics who COULD do it.

It's probably not pricey. But it's hard.
